Specific introduction
  • PF one , also known as“ platelet Surface adsorption of plasma factor V (the same as Plasma Factor V) can accelerate prothrombin transformation thrombin The role of;
  • PF two , also known as“ Fibrinogen Activation factor ”(Fibrinogen Activating Factor、 Thromboplastic material), It can accelerate the transformation of fibrinogen into fibrin monomer;
  • PF three , also known as "lipid like factor" (Platelet thromboplastin, cephalin, phospholipid)“ Thromboplastin Factor ", phosphatidylserine, participates in the reaction of factors XIII, V and X, and forms thromboplastin together with these factors;
